a The concentration of H2O2 production by different systems at 60 mA cm−2 current density. b LSVs of NADE in Na2SO4 solution with different oxygen concentrations. c The concentration of H2O2 production (0.5 h) with the change in oxygen diffusion area under different current densities. d The yield of H2O2 and the corresponding current efficiency under different current densities; the inset shows the corresponding energy consumption at different current densities. e Production of H2O2 under different current densities with the diffusion area of 0.5 cm2. Source data are provided as a Source Data file.
